You could use almost any glue for the non-engine parts. The hot glue is good because it's simple. Agree on the silver paint, it is expensive and totally unnecessary. I painted it because there was a can in the house that my SO had used for spraying pine cones to make Christmas decorations and I figure there was no point the last of it going to waste.

I'm a big believer in not throwing stuff away that could be potentially useful.
